gte(other: any): Series {
    return this.where(other, (a, b) => a >= b);
  }
Greater than or equal to of `Series` and other, element wise

pandas equivalent: Series >= val

@param {Series|Array|List|number|string} other
   Other `Series` or scalar value to check for greater than or equal to

@returns {Series}

@example
const ds = new Series([1, 2, 3], {name: 'Test name'})

// Returns Series([true, true, true])
ds.gte(1);

// Returns Series([true, true, false])
ds.gte(new Series([0, 2, 4]));

// Returns Series([true, true, false])
ds.gte(Immutable.List([0, 2, 4]));

// Returns Series([true, true, false])
ds.gte([0, 2, 4]);
